Using the finite element method, it was possible to obtain generator performance predictions based on the main parameters that could be changed such as the number of turns, the type of winding, the diameter of the enameled copper wire used in the coils, dimensions and materials of the rotor, the quantity, composition, geometry and energy product of the magnets and other parameter which will be discussed throughout this document. The comparison between the practical results of the tests performed on the generator and the simulations generated by the software proved to be satisfactory. The generator is capable of producing three-phase sine waves that have high fidelity to the ideal, obtaining a R2 = 0.9989 when comparing a voltage cycle of the generator with a sine function, in addition to a spectrum of harmonics where the most expressive (2nd and 3rd harmonic) represent, respectively, 2% and 1.7% of the fundamental amplitude, demonstrating the quality of the final product. In the load tests a satisfactory voltage regulation was obtained with a low voltage drop (see Table 5). Due to the high number of poles, in the process of rectifying the current it was possible to minimize the ripple using a low capacitance in the circuit, this implies a low investment in capacitor banks to make available the generated energy to the network. The cost of the machine, combined with the reuse of parts, provided a low cost, totaling R $ 204.00 at the end of its construction.
